Facebook CEO, Mark Zuckerberg, really wanted Snapchat. He tried to acquire Snapchat for $1 billion in October, and he offered $3 billion after a month. However, Snapchat rejected both of his offers.

Wall Street bankers used to love Snapchat. In 2013, a few college graduates picked up the app to other senior investment bankers. They used the app to communicate and share their party-filled weekends or even the industry secrets. They believed the app had a good privacy security system.
